HOISTING MACHINE. I

Application filed January 14, 1922. Serial No. 529,287.

To all whom it may concern:

Be it known that I, LUTHER M. JORDAN, a citizen of the United States of America, and resident of Sperry, in the county of Tulsa and State of Oklahoma, have invented certain newand useful Improvements in Hoisting Machines, of which the following is a specification.

This invention relates to hoisting apparatus, andparticularly to a hoisting machine adapted for use in pulling tubes, rods and casing and replacing same in oil and gas wells, the said device being intended primarily for employment in connection'with 5 motor trucks and tractors.

It is an object of this invention to produce a hoisting machine primarily adapted for use in connection with oil well derricks or masts now commonly used, and toprovide a machine of this character in which controlling levers for the mechanism imparting power to the hoisting mechanism are. in convenient position where the operator may manipulate the said levers and be stationed conveniently for the work of hooking and unhooking the hoisting cable from the tubing and rods, and in position to aid in connccting and disconnectingtubing and the like.

Furthermore, it is the purpose to so arrange the parts that the operator when manipulating the said! levers, may-be stationed in position to observe both the machine and the casing head or cap of the well, as well as the hoisting line and may better be able to know when to'start and stop the machine without danger of droppingrods or tubing,

the said invention being intended to obviate the necessity for a helper signaling when the machine shall be startedor stopped, and 1 it is therefore economical in its operation.

Furthermore, it, is the purposeof this invention to vproduce a machine having two speeds, both forward and reverse, in order that the tubing can be handled by the machine as fast as it can be assembled, a condition whichwill facilitate the placing and removing of the tubing.

Furthermore, it is an object to produce a machine having clutches on the drive shaft ratherthan on a main shaft, acondition which reduces the load they must carry, to

a very perceptible degree, and therefore in-' creases the efficiency.

It is a further object of this invention to produce a machine of the character indicated which is of simple mechanical construction involving comparatively few inexpensive parts, the cost of maintenance of which is minimized.

With the 'foregoing'and otherobjects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed. 7 I

In describing the inventlon in detail, reference will be had to the accompanying drawings forming part of'this application wherein like characters dcnotecorrespond-. ing parts in the several views, and in which-' Figure 1 illustrates a plan view of a hoisting machine embodying the invention;

Figure 2 illustrates a view in side eleva tions Figure 3' illustrates an enlargeddetailed sectional view of the brake mechanism;

I Figure 4. illustrates a perspective View of oneof the levers; and j 1 Figure 5 illustrates a perspective view of a'crank. I

In the embodiment of the invention illustrated in the drawings, 5 denotes a' base frame "which is preferably rectangular in. plan, adapted to support bearing plates 6 on which the shaft 7 of the winding drum 8 is mounted. The winding drum has brake wheels 9 and 10, one at each end, the said brake wheel 9 being embraced by a brake band 11, and the brake wheel 10 being em-- braced by a brake band 12. The ends of the brake band 11 are connected to a cross arm 18,; and the ends of the brake band 12 are connected to a cross arm' lt. The cross arm 13 is carried by ashaft 15 suitably journaled in the frame, V

and the cross. arm 14 is mounted on. a sleeve 16 which is rotatably mounted on the shaft 15, so that either the shaft or the sleeve can rotate independently of theother, for the purpose of tightening thebrake bands and checking the movement of the winding drum, The shaft 15 is partially rotated,

quadrant, and any suitable detent 22 may be employed for holding the handle at different positions of adjustment with relation to the quadrant. By this means, the brake band 11 may be drawn or released to control the rotation, of the drum. The sleeve 16 has an arm 23 by which it is partially rotated, the said arm being oscillated under the influence of an arm 24 to which it is pivoted, and the said arm 24 is, oscillated by the sleeve 25 which fits in the sleeve 19 that acts as its bearing. The sleeve 25 is operated by a handle 26, in association with a quadrant 27, similar to that heretofore described, the details of which willbe understood.

The main shaft 7 has two gear wheels 28 and 29 secured on'it, the latter being of less diameter than the former, in order to permit speed changes for increasing or diminishing the R. P. M. of the winding drum, and the said shaft is furthermore provided with the usual spool 30 employed for well drilling.

A driving shaft 31 is journaled in the frame and it has clutch pulleys S2 and 83 mounted on it, free to rotate independently of the shaft, except when clutches are actuated, as will presently appear. The pulleys are driven in opposite directions by the belts 34 and 35 respectively,and by the op eration or controlof the clutches, the winding drum may be driven in a clockwise or anti-clockwise direction. The shaft 31- has a sleeve 36 splined on it, and the sleeve has a relatively large gear wheel 37 on one end, adapted to mesh with the gear wheel 29, and a smaller gear wheel 38 on its opposite end, adapted to n'lesh with the gear wheel 28. A clutch 39 operates in conjunction with the pulley 32, and a clutch 40 operates in conjunction with the pulley '33, and these clutches are oppositely actuated to engage or disengage their pulleys by a rod 41 which reciprocates transversely of the frame and communicates motion to the levers 42 and 43 for throwing the clutches into action alternately. The mountings of the levers 42 and 43 are shown to be applied to brackets 44, the construction of which maybe modified to suit particular requirements.

The rod 41 is reciprocated under the influence of an arm 45 which arm is oscillated by the shaft 46, and the said-shaft 46'extends through a sleeve 47, which sleeve 47 is likewise rotatable in the sleeve 25. The shaft 46 is controlled or rotated by a handle 48, which may be movably arranged with respect to an arm 49 or the like that serves to hold the handle at different positions of adjustment, provision being here shown for holding it at three positions of adjustment, two of which retain one or the other of the clutches in operative engagement with the pulleys, and the other of which holds the clutches in neutral position. The sleeve 47 has a handle 50 operating in conjunction with an arm 51 that holds the handle in three positions of adjustment, in order that the sleeve 47 may be actuated to change the positions of the gear wheel 37 and 38. This last mentioned function is attained through the employment of a link 52 which has one end connected to an arm 53' oscillated by the sleeve 47, the other end of said link being connected to the sleeve actuating arm 54 which is effective to move the sleeve longi-' tudinally of its shaft31, in order that the gear wheels 87 and 38 may be caused to mesh with the gear wheels 29 and 28 respectively, or moved to neutral positions where they will be out of engagement with either of the wheels 29. or 28.

As shown in the drawing, provision is made for locating the handles that control the mechanism at one end and to the side of the frame and .at the front of the machine, in order that the operator may control the ma chine and perform other functions, part of which have been mentioned herein.

Suitable gear casings 55 may be employed for housing the operating mechanisms, but the detail construction andarrangement of these casings need not, it is thought, he illustrated or described. I

As the functions and manner of operation of the elements of the device have been stated in connection with a description of the elements, a resume of the operation-is believed unnecessary to an understanding of the device by one skilled in the art.

I claim: V
